How to Maintain White Ink

How to Maintain White Ink
Introduction
Printers with the White Ink Option require care and maintenance to ensure that the
white printheads function properly. White ink is re-circulated in the system to limit any
settling of the ink. For this to take place, the printer must be left powered On at all
times. If the printer is powered down for maintenance or service, once it is powered on
again and the ink reservoirs are full, agitate the white ink bag and perform several purges.
A new white ink bag must be gently agitated before it is connected and then at least once
a week thereafter. Daily maintenance is essential with the white ink option as it will purge
out a small amount of white ink in order to keep the printheads clear and operating reli-
ably.
Printers with the white ink option will spit into the "spit catcher" (located over the
maintenance tray) every few minutes in order to keep the white nozzles clear.
When to do
Daily
• Perform printhead maintenance every day for all colors, including white.
Weekly
• Agitate the white ink bag as described on the ink bag label (even when white is not
actively used)
• Swab all printheads
As Needed
• Purge the white printheads as required (i.e., if there are too many nozzle dropouts).
This may be necessary multiple times per day.
Before you begin
Make sure you wear eye protection and nitrile gloves when handling or cleaning ink. Also,
when working around the maintenance station take measure to protect your clothing and
any exposed areas of skin.
Attention:
Failure to properly maintain the white ink as described here can result in damage to the
printheads.
